trying to finetune I get EOFError: Ran out of input
Bug report checklist I am using the sample provided in this repo to fine tune the model based on some history data I have.
Describe the bug Getting error when running the fine tune:

The new embeddings will be initialized from a multivariate normal distribution that has old embeddings' mean and covariance. As described in this article: https://nlp.stanford.edu/~johnhew/vocab-expansion.html. To disable this, use `mean_resizing=False`

EOFError: Ran out of input
Expected behavior I expect to succeed
To reproduce
I generated 4 files using the sample code provided.
each file contains 4 series of numbers extracted from a data frame:
data.to_numpy().T
and converted to arrow files using the convert_to_arrow method
